| Abstract Scope |
Recent advances in additive manufacturing have enabled the construction of complex and multiscale architected materials. However, very few studies examine the behaviour of these lattices at the nanoscale. We investigate the mechanical properties of Nickel (Ni) and HEA (equiatomic CoCrFeMnNi) truss-based nanolattices through a combination of classical molecular dynamics (MD) simulations and Finite element simulations (FE). Scaling laws for stiffness and strength are determined for different crystallographic structures (SC, BCC and FCC). These results aim to explore the effect of scale on the performance of these structures. Furthermore, it can pave the way for developing a numerical platform for the design of materials atom-by-atom. |
